There are definitely lots of fun ways to teach math facts, and games are definitely some of my favorites. As others have mentioned, the GiggleFacts are a lot of fun, and we used programs, RightStart games, apps, and board games, among other things.
I think it depends on where you are in your math program. It sounds as though you already have a math program but just need to solidify those facts for fast recall.
I actually don’t think that flashcards are the way to go for young kids memorizing facts. Don’t get me wrong, it does work, but I think that the amount of time it takes (especially as they will get bored FAST!) isn’t worth it. It is an opportunity cost for me, primarily because I think that it takes longer for them to get to the point where they can translate that to paper with understanding and the fact that I want them to enjoy what they are doing!
We did Jones Geniuses math in the beginning to familiarize her, and eventually did RS A and B, working on facts with the RS games. Most of the games you will need to work on addition/subtraction facts can be done with a deck of cards! One of Alexs favorites was a card game called ‘Go to the Dump’, a RS variation of Go Fish. Instead of making pairs of identical cards, the idea is to pair up card combinations where the sum is 10. I find this works really well with the idea of Singapore number bonds, and it really helped Alex now that we are using Singapore math. RightStart has a demonstration video of Go to the dump on their YouTube Channel. They also have card games like addition memory, and another favorite of ours, addition and subtraction war. Addition war is simply dividing a stack of playing cards into two piles, one for each player. Then each player further divides their stack into two piles. Then both players flip over two cards and find the sum/difference. Whichever player has the greater sum/difference takes all the cards in the hand. The game is over when one player has all the cards…or when mom says that’s enough, in which case the winner is determined by the tallest stack:)

Here is another thread where I (and others) listed some more of our math fact games:

And one thing, if you like the GiggleFacts math, it is very inclusive.and while I know that it says a year for the program? Not for an EL Kid! I would be it could be mastered in A couple of months with daily play.
If you want to purchase a math games set for ALL operations and had to choose one set, I would choose the RS set. It is designed to cover a lot more and will grow with your child. The games aren’t as cute and flashy, but are mostly fun and do work.
